Maintenance: Always isolate and lock out the pump from its power source before performing any maintenance or inspection work. Beware of hot surfaces and high-pressure fluids.
Training requirement: Operators and maintenance personnel must be properly trained on the specific Warman pump model's safe operating and maintenance procedures.
2. FIRST AID MEASURES
Eye Exposure: If pumpage splashes into the eyes, flush immediately with plenty of clean water for at least 15 minutes, holding eyelids open. Seek medical attention.
Skin Contact: Wash exposed skin with soap and water. If irritation develops, seek medical attention. Pumped slurries may contain hazardous chemicals.
Inhalation: If mist or fumes are inhaled, move to fresh air. If symptoms persist (coughing, difficulty breathing), seek medical attention.
3. FIRE FIGHTING MEASURES
Flammability: The pump is not flammable, but the electric motor (or diesel engine) and some pumped materials may be. Use appropriate extinguishing media based on the material on fire.
Extinguishing Media: Use water spray, foam, dry chemical powder, or carbon dioxide (CO₂) for electrical fires involving the motor or control panel.
Fire Response: In the event of a fire, evacuate the area and call emergency services. Use appropriate extinguishers.
